yBe it known that I, CHARLES L. HnisLEn, a citizen of the United States, residing at Schenectadyin the county of Schenectady, and State of New York, have invented certain new and useful Improvements in Band- -Rolling Machinery; and I Clo-hereby declare the following yto be a full, clear, and eXact description of the saine, reference being had to the accompanying drawings, formin part of this specification. f

My invention relates'to improvements in machines for rollingbands of metal, pai'- ticularly bands ofv copper for use on shells intended to be fired' in the /larger caliber Army and Naval guns; and, theylobje'cts of my'improvements are: first, to provide a novel .set of gearing for the rolls whereby smoother action. is secured than can be ob' and efficient the reciprocating carriage for permitting insertion of the blank or hollow in'got on the mandrel; fourth, to provide an improved mandrel; and fifth, to provide a more substantial support lfor the heavy dutyv mandrel and to improve generally the connections of this element of the machine. With the above and other objects in view, 'the invention consists in certain combinations, arrangements and constructions of parts hereinafter ferred form and particularly pointed out in the claims at the end of the specification. v The various objects of my invention are obtained by the mechanism illustrated in the accompanying drawing, in which,- Figure 1 'is a central, longitudinal, vertical section showing the entire machine, in- -cludingv -the water cooling pipes' and the driving pulley.

Fig. 2 is a with th'edriving pulley omitted.

Fig. 3 is a rear end elevation partly in section particularly designed to illustrate the gearing and the piston controlled hinge arrangement of the upper or top roll, and

front elevation of the sam described in their pre? 1920. Serial N0. 399,415.

therefore omitting such features as are unnecessary for the above object.

Fig. 4 is a transverse vertical sectional view taken through the center line of the pressure cylinder.

Fig. 5 is a horizontal sectional view taken base by means of bolts passing through the lflanges of the `extended feet 11 of the legs 9 and 10.l This bed is generally rectangular in plan andin cross section, butis provided y with a pair of posts 12 rising from the rear thereof andco-operating with thehinge caps 13 to form bearings'for the hinge shaft y14 which extends practically lthe length of the machine and carries on 4its right hand end,

as viewed in Fig. 5, the hinge shaft gear 15.

The bed is also extended at the rear and side to form a gear housing 16 and at the front to form a box bracket 17 for the pressure cylinder 18 which controls the raising and lowering of theA top roll 19, this roll being carried by a spindle 20 rotatably mounted in the'top roll housing 21, the latter being a casting of considerable size and forming in effect a lever .pivotally mounted on 4hinge shaft 14- as a fulcrum by bearings 22 in eX- tensions 231and 24, and movablewabout that vshaft by virtue of the connection between arm25 andthe rod 26 .of the piston 27 in pressure cylinder 18. At the right hand housing .28. for the two similar meshing gears 15 and 29, the former being rotatably l mounted on the hinge shaft 14, while the gears,` but is provided with a removable.

cover plate -30 so positioned as to just clear the gear cover 31 which co-operateswith the.

side, as viewed in Fig. l 5, the top roll housing is enlarged to form a extension 16 to protect the lower gears 32 v and ,33,.the former' keyed to the main drive shaft 34 and the latter rotatably mounted (in a manner' hereinafter described) von la stud shaft 35 and held in angular position in the housing 16 by a key 17 and held against longitudinal movement by the, head 36 and by a cotter pin or wedge 37 bearing against the wall 38 of the bed 8.

rlhe top roll 1.9 is held in angular position on spindle by a pair of keys 40, and is held against a shoulder 41 on the spindle by means of a washer 42 secured to the spindle by a hollow cap screw 43 fitting in a" tapped hole 44 extending axially of the spindle to a transverse hole 45 drilled through the spindle so as to communicate with an annular well 46 in the interior of the roll 19. Cooling water from pipe 47 which forms a lwatertight connection with cap screw 43 passes through tapped hole 44 to the passage in the spindle and from4 there into the cooling well 46, the latter having four equi-' spaced exits 48, discharging the water into a suitable receptacle (not shown).

Power is received by driving pulley 50, which, like driving pinion 32, is keyed to a v reduced sect-ion of the main driving shaft 34 and held against a shoulder 51 thereon by the usual washer 52 held in placel by connecting screw 53.- rThe driving pinion 32 Vdrives gear33 keyed to the extended sleeve.54 of a pinion 55 freely rotatable on stud shaft or `pin 35, and pinion 55 drives the freely ro-` tatable gear 15, and through it, the gear 29 keyed to the top roll shaft, these connections,v

` 61, to -form a driving fit with the socket 62,

formed integral with the main driving shaft 34, connecting bolt 53. extending into a tapped hole 63 in the mandrel shaft, thus securing the drive and mandrelvshafts together, as well as securing same in longitudinal adjustment by the Contact of shoulder 64 on the mandrel socket 62 with the abutment 65 on the drive shaft casing 66, the latter being an integral portion of the bed 8, and' forming one wall of the socket chamber 67, the upper wall -of which is a removible cover plate 68 permitting of ready access to the coupling. The'bearing surfaces for the drive shaft and for the mandrel shaft are preferably formed of a plurality of sections of semi-cylindrical bushings 69 held in place by integral lugs 70 fitting in appropriate recesses 71 in the casing 66, the'- mandrel cap 72 and in the spindle cap 73, these two caps being secured to the casing 66 yby tmeans of stud bolts 74, similarto the stud lentering the seats and the rods.

bolts 75 which secure the hinge shaft clamps 13 to their seats 12.

Legs 9 and 10 eac-h have an upper platform machined on either side as at 81 to receive the bed 8 and provided on the lower side with two enlarged bearings 82 to serve as supports for thei guide rods '83 which reciprocate within these bearings. A

reciprocating guide 84 is mounted on vthe front end of each of the guide rods 83 and includes a pair of legs 85 extending upwardly from the guide rods and terminating in bearings 86 loosely receiving the studs 87 carried by the guide plate 88. An additional stud carried about centrally of plate 88v gages the mandrel and serves to hold the band in place on the mandrel.

At their rear ends just inside of the rear leg 10 the guide rods 83 are connected together by a cross head 94 which is provided with clips 95 which hold the rods aga-inst seats 96 on the cross head, correct positioning being secured by means of dowels 97 94 has an upward extension 98v at its rear end which receives the reduced end 99 of a Cross head piston rod 100 connected at the other end to a piston in cylinder 101. 101 is provided with a rear head 102 having the usual gland and stuffing, as shown, and

having a front head 103 which forms the support for the cylinder and piston rod.

This front head is bolted to the front leg 9 by means of an integralbracket 104 bifurcated as at 105 to clear a slot (not shown) and to provide room for the head of bolt 107, movable in said slot.

A guide roll plate cut away centrally, as at 111, to provide for reception of the mandrel, is bolted to the front leg 9 and also to the bed 8, and lcarries a plurality of band guide roll carriers 112 which support and guide the ba'nd when in its finished position. ,These guide rolls areadjustable on the plate 110 by "means of screwsl 114 threaded into lugs 115 and being held inadjusted position by means of the 'lock nuts 116. Then the lock nut is released the screw 114 may be adjusted to bring the roller 117 into proper positionby means of the squared end 118 of the .screw and may be-secured in such position by the lock nut 116.

rlhe top roll housing 2 1 ends at the front in an open chamber for the' top roll, the chamber having an open bottom, a top wall This cylinder 120, a back wall 121, and side walls 122, the latter having finished channels 123 therein to slidably receive brackets 124 carrying at their lower ends the guide rolls 125. These brackets are adjusted vertically bynuts 126 on studs 127 carried bythe top roll chamber, and areheld in such adjusted position by the headed bolts 128 carried by the sidel walls 122 and passingi through appropriate power .shaft rotatably mounted in said frame,

slots '129 in the brackets-124 and having the usual washers 130 and nuts 131.

Arm 25, which is connected to piston rod 26 by means of pin 133 held in the bifurcated ends of the arm by a cotter 134, is threaded .near its junction with the casing 21 to receive a feed screw 135 operated by a hand wheel 136 tov control the rate ofl reduction of the thickness of the band. Adjustable gages 137 threaded in bushingsv 138 may be operated by means of their squared ends 139 to bear against the upper surface of the mandrel ca'p 72, as best shown in Fig. 4. A similar gage 140'bears against the cap 73 and is lockedv in adjusted position by a nut 141 similar to the nut bearing the same numeral on gage'137.

Referring now to Fig. 1,` cooling water enters pipe 150 and passes from there to the top roll1a's previously described and also to a verticall port 151 in the back wall 121 of Ithe open chamber of the top roll housing, this port being in communication 'with a horizontal port 152 through an annular groove or channel 153 which surrounds the front bushing of the top roll shaft 20.
